Stormwater Treatment

Removing pollutants from stormwater runoff is an important component of any stormwater management plan. Stormwater pollution - sediment, trash and debris, nutrients and metals - is one of the leading causes of water quality impairment we are facing today. There are a myriad of technologies available for treating runoff - and the right system for your site should be selected based on your local requirements, your target pollutant and specific site characteristics. As no two projects are the same, there is no one size fits all answer.

Filters can help you remove the most challenging pollutants from stormwater, including nutrients like phosphorus. Though the physics of filtration are the same, there are many variables to consider when designing a stormwater filtration system. It’s critical to use a balanced approach that incorporates hydraulics, longevity and performance.

Hydrodynamic separators (swirl chamber type systems) were the initial underground water quality devices developed 20 years ago. We've been there since the beginning - and our systems are widely accepted for effective solids removal. Especially efficient on gross solids, trash and debris, they are an optimal choice for pretreatment systems.

Biofilters can provide a high level of treatment and partial runoff reduction capability above and beyond traditional systems like bioswales or raingardens. In an LID design, regulators may favor biofiltration before tradition designs are considered.
